Definitions

  • the present invention relates to a subscriber terminal for ISDN networks in the form of an ISDN telephone set according to the preamble of claim 1.
  • the application terminal connected via the connection socket for example in the form of a PC
  • the connection socket for example in the form of a PC
  • a PC must be equipped with an ISDN adapter card and a program diskette used.
  • Such an ISDN adapter card is relatively expensive.
  • the control program for the PC stored on the diskette for example, in order to make it able to communicate with the ISDN network, is relatively complex and complicated.
  • it is important that the application terminal in question is always ready for operation, but this is only guaranteed if the application terminal in question is always ready to receive, ie day and night.
  • the measures according to the invention make it possible to dispense with a separate communication module, such as the ISDN adapter card previously used, since the functionality achieved thereby, for example for the PC, is already contained in the ISDN telephone set with regard to the ISDN network.
  • the control program which previously had to be installed in the PC, is now introduced in the form of the interface mentioned in the ISDN telephone, at a point between the application program in the application terminal and the communication software in the ISDN telephone. Dei integration of this interface in the ISDN telephone allows other application terminals without hardware and / or software add-on such as communication module, remote data switching device and the like, to be connected directly to the ISDN telephone and thus made capable of communication.
  • the features are provided according to claim 2, there is a relatively simple interface, by means of which it is possible to connect a printer and / or a keyboard to the ISDN telephone set.
  • the ISDN telephone with a buffer which, with appropriate memory expansion, is able to store the incoming or received text information, which stored information can then be made visible via the printer if required. This means that the printer does not always have to be ready for operation, while the telephone set is always on anyway.
  • a "store-and-forward" operation is provided for fast monitoring via the ISDN network and for slower communication between the telephone and, for example, a PC.
  • the keyboard of the ISDN telephone set directly for sending text information, so that an external keyboard is unnecessary.
  • the display of the ISDN telephone which can be used to check the text messages to be sent, but also to make the received text messages visible next to a printer.
  • the telematics server is addressed via the service-independent interface area using, for example, the APPLI / COM protocol.
  • the envelope file for communication control and the document file are each transferred from the PC / host to the phone or vice versa. This means that both the send and receive buffers can be addressed directly from this interface area and that these memory areas can be organized.
  • this creates compatibility in the job description and the document forms between the communication software and the application programs, so that communication from application terminal to application terminal can be carried out without the information preparation or handling by the operator having to take place.
  • the features are expediently provided according to claim 6.
  • a further and thus third exemplary embodiment of the present invention results from the features according to claim 7.
  • This makes it possible to control and organize the application terminal (computer, PC, workstation) with regard to the ISDN network in such a way that direct communication, ie without buffer, is also possible in interactive mode.
  • control device It is particularly advantageous according to claim 8 to equip the control device with a command set compatible with the Hays standard AT command set for ISDN and a command set extended for the fax service.
  • Such an extended command SET can advantageously be based on the TIA / EIA-592 of the Telecommunicationes Industry Association.
  • the transmission of pure binary files is possible for the fax service according to claim 10 instead of image coding.
  • fax Gr. 3 a transparent transmission on a B channel with 64 kbit / s, i.e. done without modulating the data.
  • An expedient embodiment of the ISDN telephone set results from the features according to claim 13, although it is also possible to add an additional housing to the actual telephone set housing. However, it is essential according to the above that the interface is assigned to the ISDN telephone set as so.
  • the display of the telecommunications terminal which is present anyway, can be used for status display.
  • the single figure shows a schematic representation of the application possibilities of a subscriber terminal for ISDN networks in the form of an ISDN telephone set according to the present invention.
  • a subscriber terminal suitable for connection to the ISDN network is shown schematically in the form of an ISDN telephone set 11.
  • This ISDN telephone set 11 has a housing 12 with, for example, a telephone receiver 13 lying on the side, with an alphanumeric display 14 and two groups 15 and 16 with alphanumeric and symbol keys 17.
  • the ISDN telephone set 16 is also provided with a connecting cable 18 for connection to the ISDN -Netz and also provided with at least one connection socket 19 for external application terminals, as they will be referred to below.
  • the ISDN telephone set 11 is equipped in such a way that one or more application terminals, such as a printer 21 or an external keyboard 22 or a fax machine 23, or a word processing system, for example an office PC 24, a workstation or the like, can be made capable of communication via it, without the application terminal or terminals in question having to be provided with special communication modules (hardware and software) and data remote switching devices.
  • the PC 24 comprises, in addition to a drive station, an input keyboard and a screen, also a printer and a scanner, so that it can be used both for text-oriented services (Teletex, Telex) and for graphic-oriented services (fax) via the telephone set 11 can be used on the ISDN network.
  • an interface (hardware and software) is integrated in the ISDN telephone set 11, with which the communication capability between the application terminal 21, 22 or 24 to be connected and the ISDN network can be established.
  • the interface is either installed in the apparatus housing 12, as can be seen from the drawing, or it is accommodated in a detachably connected additional housing 20, as shown in broken lines.
  • the application terminal to be connected is not a communication terminal in itself; it is only through the interface integrated in the ISDN telephone and its assignment.
  • the interface integrated between the application part in the relevant application terminal and the communication part in the ISDN telephone set 11 has a so-called telematics server, which represents a program part which (according to the OSI reference model) is above layer 3, ie in layers 4 to 7 is introduced, in which the D and B channel of the ISDN network is normally organized and is processed.
  • This program part or this telematics server which works for a simple interface specification in layer 7, is designed such that, as is realized in a first exemplary embodiment, when a printer 21 and... With the connection socket 19 of the ISDN telephone set 11 / or a keyboard 22 is connected, this or these terminals is or are capable of communication with the ISDN network via the ISDN telephone set 11.
  • a buffer (as part of the communication part) is integrated in the ISDN telephone set 11, which is so large that incoming messages and messages to be sent can be stored in the ISDN telephone set 11.
  • the incoming messages are stored until the messages are retrieved using the printer 21.
  • the messages to be sent are stored in the form of a buffer, with the aim of transmitting the messages via the ISDN network from the buffer, that is, not directly ( "Store and Forward" operation).
  • Printer 21 and keyboard 22 create simple and inexpensive application terminals.
  • the interface provided with the telematics server in the ISDN telephone set 11 is expanded by a service-independent interface area, specifically in the form that a specific interface specification in layer 7 of the control communication part of the ISDN telephone set 11 is provided.
  • This interface specification is, for example, the APPLI / COM telecommunication interface, as is the result of a joint campaign by the Deutsche Bundespost TELEKOM, the Hätation Stamm- Kommunikation and some manufacturers of telecommunications equipment is standardized (see the brochure "APPLI / COM, the standardized telecommunications interface", version 1.0, as of July 1990, publisher: Deutsche Bundespost TELEKOM, Fernmeldechnisches Mont, Darmstadt).
  • This APPLI / COM interface is located between the application part and the communication part and enables the communication capability of different services, such as Teletex and Telex as a page-oriented communication service as well as fax as a graphics-oriented communication service with the ISDN network.
  • This APPLI / COM interface specification enables the buffer to be organized and controlled, which is divided into a transmit memory area and a receive memory area in the ISDN telephone set 11.
  • the service-independent interface area provided with the APPLI / COM interface specification is replaced by an interface area in which a control program part is integrated, with which the relevant telephone functions can be remotely controlled and with which messages are sent directly to the ISDN network, i.e. bypassing the above Buffer can be brought.
  • AT command set program is used as such a control program part, as described in the publication "Hayes Standard AT Command Set, Enhanced for ISDN, Release A, November 30, 1989” by Hayes Microcomputer Products, Inc., Atlanta , USA ".
  • this control device integrated in the interface area, direct access to the ISDN network via the ISDN telephone set 11 is possible. This means that the ISDN line can be set up immediately without the need for a buffer.
  • a modem is integrated into the ISDN telephone set 11 that understands the control program, for example in the form of the AT command set, and in this way makes the relevant application terminal for the service in question not only capable of communication with the ISDN network, but also that essential functions, such as establishing the connection, direct data exchange, terminating the connection and the like organized and remote controlled.
  • control device contains, in addition to the Hayes-compatible AT Command SET standard for ISDN, which forms a control program part, an extended control program part for the fax service.
  • This extended part of the control program carries out a bidirectional protocol conversion.
  • the application terminal side e.g. implemented by the PC, a protocol TIA / EIA-592 of the Telecommunications Industry Association proposed in the standard into a protocol T.30 CCITT for the transmission sequence with an image coding according to T.4 CCITT on the ISDN network side.
  • the protocol TIA / EIA-592 corresponds to the standards proposal no. 2388-B Proposed New Standard "Asynchronous Facsimilie DCE Control Standard" of the TIA from March 13, 1992.
  • Table 1 shows the sequence for the transmission mode.
  • Column 4 shows the necessary actions of the remote station (column 4, "Remote Station Action”) and column 5 (column 5, "Notes”) additional comments can be found.
  • parameters e.g. Identity of the calling / called terminal and the transmission speed.
  • FDT Fax Data Transmission
  • Table 2 shows the procedure for the reception mode. Columns 1 to 5 correspond to columns 1 to 5 of table 1.
  • the service can also be transparent, i.e. instead of the usual modulation / demodulation of the data. transmitted unmodulated over a B channel with 64 kbit / s.
  • the subscriber terminal according to the invention that, because of the displays which are present anyway, the parameters characteristic of the respective application terminal can also be carried out at any time in the form of a status display. In particular with the fax service described above, e.g. the transmission speed are displayed.
  • connection socket 19 for, for example, teletex and fax communication via two separate computers (PC or other workstations).
  • the ISDN telephone set 11 is provided with a switch with which the different interface areas and thus the different possibilities can be switched on depending on the integration or expansion level of the telephone set 11.
  • none of the application terminals used is a dedicated communication terminal, but rather a "normal" device, such as a computer (e.g. PC, usual workstations), keyboard board or printer, which is dedicated to its own operation.
  • the relevant application terminals can only access the communication services offered by the ISDN network by integrating the text and / or graphic-oriented communication functionality into the ISDN telephone set.
